Sodium carbonate was used to precipitate silver from a solution. 6.00 grams of silver carbonate were recovered 1.500L of solution. What was the concentration in ppm of silver ions in the original solution? You may ignore ionic strength and coupled equilibria. The Ksp for silver carbonate is 8.1*10^-12. Assume water has a density of 1.00g/ml.
Calculate the fraction of atoms in a sample of argon gas at 391 K that have an energy of 12.7 kJ
